Seachoice 50-15543 Reed Switch Fuel Sender – 9.2 in. (230mm)
Keep your fuel readings accurate and your sender reliable. The Seachoice 50-15543 is a 9.2-inch (230mm) reed switch fuel sender designed for shallow marine fuel tanks, compatible with the standard 33 ohm (full) / 240 ohm (empty) gauge resistance range used across most marine fuel gauge systems.
The reed switch design has no moving mechanical parts — eliminating the most common failure point in traditional float-arm senders. Stainless steel immersion tubes resist corrosion in fuel environments, and the included SAE 5-hole gasket makes for a clean, straightforward installation on standard tank openings.
Key Features
- 9.2 in. (230mm) sender length — designed for shallow marine fuel tanks
- Reed switch design: no moving parts for maximum durability and long service life
- Compatible with 33 (full) / 240 (empty) ohm fuel gauges — the most common marine standard
- Stainless steel immersion tubes for corrosion resistance
- Corrosion-resistant plated mounting flange
- Includes gasket with SAE 5-hole bolt pattern
- 0.250 in. insulated spade connectors
- Part Number: 50-15543 | Barcode: 719249155431
Best Use Case
Best suited for replacing a worn or inaccurate fuel sender in a shallow marine fuel tank (approximately 9 inches deep). If your fuel gauge is reading erratically and the gauge itself tests correctly, the sender is the most likely cause. This unit is a direct drop-in for most OEM tank configurations using the SAE 5-hole mounting pattern.
